%X Using Field single ignition experiments of the four unconfined volume dispersion and small dosage solid FAE and TNT bombs experiments,we got the peak overpressures of solid FAE at different distances.Compared with TNT,The overpressure of FAE is 1.14~1.6 times higher than that of the TNT.Based on the theory of the air shock wave overpressure,the FAE relativity TNT mass is evaluated.At the edge of the explosive field,the number is 3.88.Pictures of high speed photography indicate that the duration and the most effect area of the FAE and TNT.Compared with TNT,obviously the FAE has more advantages.And,based on the theory of the critical concentration of dust explosion,the radius of dust explosive zone is evaluated.The phenomenon that the overpressure decays rapidly with distance is analyzed.It is suggested that the explosive temperature should be increased as the main approach to improve the FAE explosive capability in the condition when the over pressure is invariable.
